I never watch it, but I think the first name on any list has to be The Lone Gunman.
Comrade Sugarman's knowledge of all things spidery is surely vital for any jungle challenge.
Next name is obviously Croesy. He is bound to maintain peace and civility as discomfort and stress rise in the group, as evidenced by his selfless struggles for harmony over many years on this board. A saint of a man!
